int_(0)^((pi)/(2))(2log cos x-log sin2x)dx

Evaluate : int_0^(pi/2) (2 log cos x-log sin 2x)dx .

Prove that int_(0)^(a)f(x)dx=int_(0)^(a)f(a-x)dx and hence evaluate int_(0)^(pi//2)(2log sin x-log sin2x)dx .

The value of int_(0)^(pi//2) (2log sin x-log sin 2x)dx , is

The value of int_(0)^(pi//2) (2log sin x-log sin 2x)dx , is
